No include option

Plugin good but why you not include “Include” option.
Suppose i have 50 page in website then i just want to show only 4 pages in site map page
then instead of doing [simple-sitemap show_label=”false” links=”true” page_depth=”1″ order=”asc'” orderby=”author” include=”115,169,331,13″]
I have to do this
[simple-sitemap show_label=”false” links=”true” page_depth=”1″ order=”asc'” orderby=”author” exclude=”115,169,331,13,33,107,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28…….so on”]
